Research interests

Dr John P Foran's academic research is clinically orientated and focuses on: 

  • new and emerging therapies to prevent embolic/haemorrhagic stroke in high-risk patients with atrial fibrillation; 

  • diagnostic (intracoronary imaging) and interventional techniques (calcium modification) to improve patient outcomes following percutaneous coronary stent implantation; 

  • emerging interventional treatments for patients with resistant hypertension.  

In 2003, Dr JP Foran pioneered left atrial appendage closure (LAAC) here in the UK.  LAAC is a key-hole interventional technique employed to reduce the risk of stroke and systemic embolism in high-bleeding-risk atrial fibrillation patients as an alternative to oral anticoagulant therapy; he now has nearly 20 years of experience in this field.
